MEANS FOR REENFORCING CONCRETE FLOORS.

' Application filed November 12,1928.

This invention relates to means for reen- [(jl(fll12f concrete or other cementitious floors, and has for its particular object to facilitate the positioning and maintenance of the reenforcing members in proper spaced relation.

The art of reenforcing cementitious floors as now practiced, consists in positioning longitudinally and transversely extending reenforcing bars onto the floor or support, preparatory to pouring the mush concrete or other material therearound. Obviously, while these bars may be properly positioned at the outset, they often become displaced or disturbed by the travel of the workmen back and forth across the floors, or by other disturbing influences, whereupon the reenforcing bars are moved out of alignment, and when the concrete is poured, portions of the floor are over-reenforced while other portions are under-reenforced.

It is therefore, the particular object of this invention to provide a system of reenforcing elements so constructed that they may be positively held in fixed spaced relation so that when the concrete or other cen'ientitious material is poured therearound, they will be in proper spaced relation to provide e'tlicient reenforcement.

The invention has for its object, furthermore, to provide a system of reenforcing members which may be quickly and easily positioned prior to pouring the concrete, thus materially cheapening the cost of producing reenforced cementitious floors.

The novel features of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein;

Figure 1 is a fragmentary plan view, partly in section, of asection of the reenforcing members;

Fig. 2 is a vertical sectional view, through the reenforcing members as they appear before the concrete is poured; and,

liig. 3 is a fragmentary detail view.

Referring now particularly to the drawings wherein like reference characters indiate like parts, it will be noted that there is illustrated a flooring or support 10 of the building, upon which the cement floor is to be placed. The reenforcint; means consists of a plurality of longitudinal bars 1]., arranged in spaced parallel relation, and a ranged in spaced parallel relation.

plurality of transverse bars 12, also ar- Serial No. 674,210.

Each transverse bar is formed with a plu rality of sections 13, successively inter-connected. Each section has one of its ends 1 1 bent angularly to form a supporting leg, while the other end thereof is'bent to form a hooked end or tongue 15 designed to. enter a recess or opening 16' in the next adjacent section, to interlock or connect the sections.

The connections between the sections 13 are so arranged that these sections overlap, each section 13 at the overlapping end opposite from the supporting leg 14:, being formed with an offset portion or recess 16, shaped to receive the adjacent transverse bar 11. Inasmuch as this offset is formed in the overlapped end of each section 13, the bar is supported between the offset 16 and the underlying adjacent end of the next section 13, as is clearly illustrated in Fig. 2. Thus the bars 11 are supported spaced from the floor 10 and in spaced parallel relation to one another.

Each transverse bar 12 is preferably formed with an end section 17, which is substantially U-shaped in cross section, and is formed with a pair of legs 17 v The sections of the transverse reenforcing members may be apertured at suitable intervals for the reception of securing elements, 18, which may be passed therethrough, and into the support 10, for the purpose of positively positioning the trans verse members.

In practice, members 12 will be laid section by section, each section 13 that is being laid, being first raised to the angular position illustrated in dotted lines in Fig. 3, so that the lip or tongue 15 thereof may engage the aperture 16 of the previously laid section, and the offset 16 thereof caused to straddle the longitudinal bar 11, which has been laid transversely of the section 13. As mentioned, the transverse members may be secured in position by the means 18 passed therethrough,and driven into the flooring foundation 10.

From the foregoing it will be immediately apparent that a system of reenforcing'memhers is provided which may be successfully employed for efficiently reenforcing a cementitious floor throughout, inasmuch as after the reenforcing members are placed in position, liability of the same becoming displaced is eliminated. Furthermore, the method of inter-connecting the sections of the transverse members, and of effecting a connection between these transverse members and longitudinal members, enables the rapid positioning of the same, thus materially reducing the cost of producing reenforcing, cementitious floors.

While one embodiment of the invention has been illustrated herein in some detail, it is not intended that the invention be unnecessarily limited, but reservation is made to make such changes in the specific form illustrated as may come within the purview of the accompanying claims.

Having thus described the invention What is claimed is:

1. Reentorcing means for cementitious floors comprising longitudinally and transversely extendii'igreentorcing members arranged in spaced relation, each of said transverse members consisting of a plurality of sections, each section being formed with a perforation and a hooked end, the hooked end of each section engaging the perforation of the next adjacent section, each section being shaped to engage one of the longitudinal members the opposite end of each section being angularly bent to torn: a supporting leg.

2. Reen'forcing means for cementitious floors comprising longitudinally and transversely extenoing reentorcing members arranged in spaced relation, each of said transverse nien'ibers consisting of a plurality of sections, each section being formed with a perforation and a hooked end, the hooked end of each section engaging the perforation of the next adjacent section, each section being: shaped to engage one of the longitudinal members, the opposite end of each section being angularly bent to form a supporting leg, said sections being formed with apertures and means passing through said apertures and into a support for securing said members in place.

In testimony whereof, I aflix my signature.
